Videos can be narrated by the voices from Cognizy's cast or by brand voices: saved from the library (no cost to save), created from a description, or cloned. The default voice is the one used for new videos.

Creating your own voice costs 30 credits, one time. Saving from the library is free.
A company can have up to 5 own voices and 10 from the library.

Step by step

Step 1:
Open Izy Studio › Voices and click Voice Library.
Step 2:
Filter by gender, age, and use (ad, conversation, narration…), listen to the preview, and click Save on the ones that fit the brand. They'll then appear in the voice selection for videos and avatars.
Step 3:
For a voice exclusive to the company, click Create by Description: choose female or male, describe what the voice sounds like, and click Create 3 Previews (free). Listen and save the one you choose.
Step 4:
Saved and created voices appear under Brand Voices. In each one's menu, Set as Default, Rename or Delete. Deleting removes the voice from Cognizy; videos already narrated keep their audio.
Step 5:
In Cast, the voice marked as Default is the one used for new videos. To switch, click Set as Default on the voice you prefer.
